*Prices are shown after applying the 30% federal tax credit.
As of Apr 2024, the average cost of solar panels in Narragansett is $2.44 per watt making a typical 6000 watt (6 kW) solar system $10,261 after claiming the 30% federal solar tax credit now available.
This is lower than the average price of residential solar power systems across the United States which is currently $3.00 per watt.
The size of a solar panel system also plays a role in how much the installation will cost.
Larger solar installations will typically have a lower cost per watt, because the panels can be purchased at a ‘bulk price’. However, these larger solar systems will still have a higher total cost, because they are made up of more individual panels.

Sunenergy installed 42 panels on our house which is calculated to provide 100% coverage over the course of the year. Installation was completed as scheduled. The installation team was courteous and left the property immaculate. Our sales rep, John Parlatore, explained every step and kept us informed throughout the process answering all our questions. It was a pleasure working with sunenergy. While it is early to know the full impact of the panels on our monthly bill, we are confident that we made the right decision.

Couldn't be happier with the results. We chose to install panels and the solar battery and its been great. The NEC Solar staff were friendly and polite when installing and seem to have done a great job. We have had some rough storms and everything has been fine. The support after installation has also been great. I had to reach out to them earlier this year (over a year after installation) as I had a leak through the roof and was instructed to contact the solar company as they may have damaged the roof. The team came out within a day and went onto the roof and confirmed everything looked fine (and that it was actually the area around the chimney which looked like the culprit). A roof company came and repaired the chimney which had nothing to do with the installation from NEC Solar. We didn't have the panels installed until fall of 2022 so we didn't see much of a result (which was expected). In 2023, my electric bill was 0 from April-November. My entire house runs on electricity and I work from home and am using lots of electricity. The solar battery also works very well. There was a storm earlier this year knocked out the power lines and we had no power for almost a whole day and we didn't experience any effects in our house as the battery system immediately kicked in. Lastly, I love that I can view the solar production and manage the battery through the website/app. Very convenient. Whatever your reasons--be it environmental or to save a ton of money (my reasons) or some other reason, go with a local company like NEC Solar--I highly recommend!

New England Clean Energy Clean, courteous, hard working and meticulous are only a few ways to describe installation crew that professionally installed my families PV solar system on our home. My wife and I were hesitant to make such a drastic change and investment to our home but New England Clean Energy made it a pressure free experience and we have been ecstatic with our decision. We met with over a dozen solar companies and many proved they would not be able to meet our high standards. From Mark in sales to the site supervisor JJ, New England Clean Energy proved they were right choice and delivered as promised!

I never thought I would go solar but from the salesperson to follow up it was so professional, real customer service! The installation team was so efficient so instructive and so professional. So if you want to go solar strongly suggest you do go Venture Solar. I am so enjoying watching my net meter going backwards since the installation, it looks like I with Venture Solar will produce 100% of my electricity needs!

Very skeptical at first probably like everyone else. The sales team with Dylan, answered all my questions from the actual solar panels and equipment to the service and warranty I would expect. He was outstanding knowledgeable and readily available for my many calls. As for the team the electricians Ray and Jarret went the extra mile for panel placement, conduit hidden very well wiring in the attic on a hot day. Both extremely knowledgeable for many more questions. The roofers Jason and Juan were neat did a fantastic job and I am pleased with the appearance. 6 hours installed perfectly. Unfortunately the slowest process waiting for RI Energy to change out my meter. I would highly recommend RTP over anyone else. They truly are a team.

I highly recommend Sol Power. Every step of the way, they were professional, above-board, and efficient in their planning, installation, and wrap-up process. We even got the installation finalized through the pandemic! Plus they are cooperative, which keeps the money in the community.

The sales process was great. They were very attentive and offered the best deal on the best equipment. Then.. After signing the deal, they stopped returning e-mails and phone calls. It took them 6 months to get the materials delivered. Then it took 2 weeks before installation started. And the meter was installed incorrectly. They corrected that quickly as I was still holding the final 10% progress payment and their sales team was back to calling and e-mailing every other day. 4 years in, one of the micro-invertors stopped working. For 4 weeks, no one at RGS responded to my calls; e-mails; or web-chats. I initiated the replacement part request with the manufacturer and the next day RGS e-mailed me back to say a replacement part had been ordered and should be arriving in 2-4 weeks. I got the part in 4 weeks, notified RGS, and, again, they went silent on me. 4 weeks after that, I got an e-mail from RGS with a workorder stating that I would have to pay $350 plus additional costs for them to complete the work under warranty. That is where we stand now. If I had to do it again, I would go with a company that had positive reviews after the sales process. That is when you are going to need them they most. Good luck with your solar projects.

After comparing prices with other companies SunWatt had the most value without any inflated system performance predictions. Every part of the system, the incentives and the return on cost was carefully explained during the sale. Fast, professional installation. Excellent performance of the system. Happy to be helping the environment and lowering my energy costs.

Working with Greenside Energy was an unbelievable experience. We got a half dozen proposals from installers before we pulled the trigger. Greenside didn't just sell us a solar system but educated us about all the componets like the inverters, power optimizers, snd solar panels. They set us up with an amazing web based monitoring portal so we are able to track our power production in real time. After The install was complete they used their quad copter to take an aerial photo of our system which we have hung up in our office! I would highly recommend giving them a call.<br /><br />West Main Self Storage Team

Where there is no specific pricing information available for a brand then we have used state pricing data for that brand.
Solar panel manufacturer | Avg. cost per watt |

Panasonic | $2.75 |
LONGi Solar | $2.20 |
The most important difference between buying solar panels and any other purchase is that solar panels last 25-30 years. This is a long, long time and you will need customer service over all that time. The reviews below of the two largest corporate solar installation companies indicate larger corporate solar companies are not delivering this support to their customers.
We recommend you find a small or mid-size, local, family-owned solar company. These companies tend to care more about you and your specific job. You don't want to be on hold to a corporation's call center for the next 25 years!
The cost of solar doesn't just include the equipment and installation costs - it’s also made up of permitting costs, inspection costs, and installer profit margins.
These different components are what make the price of solar fluctuate between installations. Some of the factors that affect solar power system installation costs for specific homes include:
Homes that use more electricity will need more solar panels to cover their energy needs.
Although solar panels do get cheaper on a per-watt basis, the overall cost of the system will increase as more panels are added.
But, the higher a home’s energy usage, the more solar panels can save the homeowners on their energy bills.
The price of solar panels can vary depending on the type of solar panels you choose.
There are two main types of solar panels for residential solar installations: monocrystalline and polycrystalline. Monocrystalline solar panels tend to be more efficient and more expensive than other solar panels. Polycrystalline panels have a lower efficiency rating and come at a lower price point.
The type of inverter you buy will also influence the cost of your solar system.
You may see some solar quotes with prices that seem too good to be true.
If you get quoted for a ridiculously cheap price, the installer might be using low-quality equipment or an unsustainable pricing model. You want to use a solar installer that is charging enough so that they can stay in business - as you’ll be relying on them for the next 25 years!
It’s important to make sure that your installer is giving you the best quality at the best price possible. This is why getting multiple solar quotes is so important.
The overall cost of solar can be influenced by the solar incentives available.
Across the U.S., homeowners can apply for the federal solar tax credit. The solar tax credit makes installing solar more cost-effective by providing homeowners with a tax credit equal to 30% of the cost of their installed solar panel system.
Local solar tax incentives and rebates can end up saving homeowners thousands on a solar installation, especially when they’re used with the federal solar tax credit.
See what solar incentives are available in your area by using our solar panel calculator.
The cost of installing residential solar panels in Narragansett varies with the brand of solar panels and inverters you choose, the installation company you choose to install them, the relative ease or difficulty of installing solar panels on your home, and of course the amount of solar panels you need. The amount of solar panels you need is, in turn, related to your energy usage.
The table below shows the data extracted from a real life quote delivered through the SolarReviews marketplace recently for a fairly typical home in Narragansett.
As you can see the payback period is relatively short and equates to a much better return on investment than he historical returns that have been available from investing in things like shares or property.
